A new report by the Natural Resources Defense Council says even though gas is getting more expensive, U.S. drivers could save 68 billion dollars under new fuel efficiency standards set to be implemented in 2030. The study predicts drivers in Texas will save the most. It says Texans could save about seven billion dollars under a 54-mile-per-gallon standard. Auto industry analyst Alan Baum says automakers are already creating new vehicles in advance of a 35 mile-per-gallon standard that goes into effect in 2016. That includes popular pickup trucks.

"The consumer can pick the vehicle they want to serve their purpose and then find vehicles that have much better fuel economy."

And Baum says he's seeing more people buy new vehicles because of high gas prices.

"People are coming in and saying, I understand I've got a lot more choice here, there's better fuel economy, and I don't have to make a compromise in buying my vehicle. Please get me out of this thing and sell me a new product."

The study found there are 57 fuel-efficient vehicle models now in showrooms. That's compared to 27 models three years ago.
